Chapter 1515-32If the version of the Suddle Controller PCB, SDL-STCH software is earlier than Ver. 4.01, update the software to Ver. 4.01 or later, and perform the samejob again. The SDL-STCH software Ver. 4.01 and later has modifications to the fault that the paper folding position shifts by about 0.25mm every time thefinisher unit performs the saddle-stitch operation.15.3.3.3 Noise15.3.3.3.1 Abnormal noise occurs at delivery: Inlet roller bushing of Finisher-Z1 is detached from end plate0016-1353Color iR C3380G / Color iR C2880G / Color iR C3380i / Color iR C3380 / Color iR C2880i / Color iR C2880 / iR C3480 / iR C3480i / iR C3080i / iR C2550[ Inspected by Canon Inc. ]DescriptionSince abnormal noise occurred because of the detachment of the inlet roller bushing of the Finisher-Z1 from the end plate, the bushing was re-fitted forsolution.Field RemedyWhen abnormal noise occurs at delivery, check if the inlet roller bushing of the Finisher comes off; if so, re-fit it.15.3.3.3.2 Abnormal (rasping) noise occurs upon power-on or during printing: Developing drive assembly is faulty0018-1348Color iR C3380G / Color iR C2880G / Color iR C3380i / Color iR C3380 / Color iR C2880i / Color iR C2880 / iR C3480 / iR C3480i / iR C3080i / iR C2550[ Inspected by Canon Inc. ]DescriptionSince abnormal (rasping) noise occurred upon power-on or during printing, the developing drive assembly was replaced with a new one for solution.Field Remedy1. In service mode > COPIER > Function > PART-CHK > MRT, enter '2' (developing motor 2) and press [OK], then press [MTR-ON] to check the operatingnoise of the motor.2. If the occurrence of the abnormal noise is confirmed, replace the developing drive assembly with a new one.F-15-453. Check to make sure that abnormal noise has been solved.FM2-5568 Developing Drive Assembly15.3.3.3.3 Abnormal (squeaking) noise occurs shortly after paper delivery: Fixing assembly is faulty0018-7047Color iR C3380G / Color iR C2880G / Color iR C3380i / Color iR C3380 / Color iR C2880i / Color iR C2880 / iR C3480 / iR C3480i / iR C3080 / iR C3080i / iRC2550[ Case in the field ]DescriptionSince instantaneous abnormal (squeaking) noise occurred shortly after paper delivery, the fixing assembly was replaced with a new one for solution.CauseThe noise seems to be squeaky rubbing sound caused when the fixing assembly stops after paper delivery.Field Remedy1. In service mode > COPIER > Function > PART-CHK > MTR, enter the code of a motor to be checked, and then get the motor to work by selecting MTR-ON in order to identify the source of the noise. (In the above-mentioned field case, the fixing motor (M3; motor code is "3") was the source of the noise.2. If the noise source is the fixing motor, replace the fixing assembly with a new one.FM2-9986 Fixing Assembly (120V)FM2-9987 Fixing Assembly (230V)15.3.3.3.4 Abnormal (squeaking) noise occurs from fixing assembly: At delivery area of fixing assembly, delivery roller shaft and bushingwear out0018-7905Color iR C3380G / Color iR C2880G / Color iR C3380i / Color iR C3380 / Color iR C2880i / Color iR C2880 / iR C3480 / iR C3480i / iR C3080 / iR C3080i / iRC2550[ Inspected by Canon Inc. ]DescriptionSince abnormal (squeaking) noise occurs because of wearing of the delivery roller and busing at the deliver area of the fixing assembly, conductive grease
